A 58-year-old man is brought to the emergency department by emergency medical services after vomiting a large amount of bright red blood. He has a past medical history of alcoholic cirrhosis and admits to recent noncompliance with his home medications. On arrival, he is lethargic but arousable. His temperature is 36.5°C (97.7°F), blood pressure is 88/54 mmHg, heart rate is 122/min, and respiratory rate is 22/min. Physical examination reveals scleral icterus, multiple spider angiomas on the upper chest, and a distended abdomen with shifting dullness. His extremities are cool and clammy. Two large-bore peripheral intravenous lines are immediately established, and rapid resuscitation with isotonic crystalloid is initiated. Blood type and crossmatch are sent to the laboratory. Which of the following is the most appropriate next step in the acute medical management of this patient?

  1. Intravenous octreotide and intravenous ceftriaxoneCevap
  2. B
    Emergent transport to the endoscopy suite for esophagogastroduodenoscopy
  3. C
    Intravenous pantoprazole and intravenous meropenem
  4. D
    Computed tomography angiography of the abdomen
  5. E
    Intravenous propranolol and placement of a balloon tamponade tube

Cevap

Intravenous octreotide and intravenous ceftriaxone
The correct answer is intravenous octreotide and intravenous ceftriaxone. In a patient with cirrhosis presenting with acute upper gastrointestinal bleeding (which is highly likely to be variceal), mortality is strongly associated with both failure to control the initial hemorrhage and subsequent bacterial infections, particularly spontaneous bacterial peritonitis. Consequently, empiric medical management must be initiated concurrently with volume resuscitation and prior to endoscopy. Octreotide is a somatostatin analog that induces splanchnic vasoconstriction, thereby decreasing portal venous blood flow and reducing variceal pressure. Prophylactic antibiotics, specifically a third-generation cephalosporin like ceftriaxone, are considered standard of care as they have been definitively shown to reduce the risk of infectious complications, decrease rebleeding rates, and improve overall survival. Once the patient is medically optimized and hemodynamically stable, urgent esophagogastroduodenoscopy (EGD) should be performed (typically within 12 hours) for definitive diagnosis and therapeutic intervention, such as variceal band ligation.

Adım Adım Çözüm

1
Identify the clinical presentation and likely diagnosis.
The patient has a life-threatening upper gastrointestinal hemorrhage in the setting of known alcoholic cirrhosis, highly suspicious for ruptured esophageal varices.
Massive hematemesis in a cirrhotic patient with signs of portal hypertension (ascites, spider angiomas) points directly to variceal hemorrhage.
2
Assess the patient's hemodynamic status.
The patient is in hypovolemic shock, evidenced by hypotension (88/54 mmHg), marked tachycardia (122/min), and cool extremities.
Recognizing shock dictates that immediate stabilization must precede any invasive diagnostic procedures.
3
Determine the sequence of acute management for suspected variceal bleeding.
Before diagnostic endoscopy, patients require volume resuscitation, splanchnic vasoconstrictors, and prophylactic antibiotics.
Medical management decreases portal venous flow and prevents life-threatening infections, both of which are strongly correlated with reduced mortality.
4
Select the appropriate pharmacotherapy.
Intravenous octreotide and intravenous ceftriaxone are the standard of care.
Octreotide causes splanchnic vasoconstriction to reduce variceal bleeding, while ceftriaxone covers common enteric pathogens to prevent spontaneous bacterial peritonitis and bacteremia.

In patients with cirrhosis presenting with acute upper gastrointestinal bleeding, immediate medical management with a splanchnic vasoconstrictor (octreotide) and prophylactic antibiotics (ceftriaxone) must be administered alongside volume resuscitation prior to definitive endoscopy.
